BlLGE-WATER EJ ECTO R.

SPECIFICATION forming part of Letters Patent No. 333,753, dated January 5, 1886. Application filed March so, has. Serial No. 160,687. (No model.)

To all ulhom it may concern:

Be it known that I, GEORGE HAYDN, acitizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bilge- Water Ejectors, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to bilge-water ejectors; and it consists of two cone-shaped casings, one within the other, arranged with a check-valve automatically operated, and a positive cut-off valve which may be operated from any part of the vessel, as illustrated in the accompanying drawings, in which Figure l is a side view of the vessel, with part in section, showing the location of the device; Fig. 2, a detail view on line 00, showing the top plate of the cutoff valve; Fig. 3, an end view showing the inlet-opening of the ejector; Fig. 4:, a sectional detail view of the ejector and the valves as located or arranged in relation to the bilge-well.

Similar letters refer to similar parts throughout the several views. a

The letter A designates the hull of the vessel, provided with the usual bilge-well, a, to which is connected the ejector B, which is secured to the outside of the vessel below the water-line. The ejector B consists of an outer cone-shaped casing, 12, provided with an opening, 2), which connects with the bilge-well a, and through which the bilge water is removed from the well. Inside of this casing 12 is placed a second cone-shaped casing, c, the large end 0 of which is secured to the large end of the outer casing, b, (by soldering or any other way that will make a water-tight joint between the two,) with the small end 0 less in diameter than the like end of the outer casing, thus forming around the exterior of the inner casing the passage (1, through which the bilgewater passes to the exit-port e, where it is discharged by the action of the water that is being forced from the opening 0 of the inner casing by the forward movement of the vessel. To the ejector B is secured ancck,f, which leads to the bilge-well, and in which is placed a check-valve, g, and a cut-off valve, h, the check-valve consisting of a central stem, 9,

provided with a square opening, 9 at itslower end, that engages with the square 8 on the cutoff valve, and its upper end provided with the square g", that enters in and engages with the square opening 70 in the deck-stem i, thereby forniing a guide by which the valvestem g is held in its place. and at the same time forming a connection between the cutoffvalve h and the deck-stem 'i, thelatter operating the valve h, as set forth hereinafter. The stem 9 is also provided with a float, Z, consisting of cork or any suitable material, the buoyancy of which when there is back-pressure from the exterior water lifts the stem 9 and presses the leather or gum m placed thereon against the seatn, there being sufficient up and down play in relation to the squares g and g to permit the same, thus preventing any water from passing back into the vessel; but in case the check-valve g should get out of order I provide the cut-offvalve h, consisting of a pivoted plate, 11,, provided with the holes 1), which are so arranged that when the plate a is turned to a certain position they are placed opposite to similar arranged holes in the partition 0, thereby opening communication between the bilge-well a and the ejector B, and the same out off or closed by a partial rotation of the stem i, which, through themedium ofthe stem acts likewise on the plate a. The connection of the stems i and g and their operation are as before stated.

The operation is as follows: Then the vessel is under headway,the exterior water passes through the opening 0 with an increased velocity caused by the mouth or opening 0 having a greater area than that of the opening 0 thereby forming a pressure at the opening 0 equal to the resistance of the area at the opening 0', which forces a stream of water bacl; to the exit-port e, by which a vacuum is formed in the passage d, that starts the water to flow from the bilge-well, and which is ejected with the stream from the port 0 through the exitport e, thus affording means by which the bilge-water is ejected from the vessel automatically.

The casings b and 0 may be cast integral or made in separate pieces and secured together, or a greater number of the cone-shaped parts may be arranged, if desired. Therefore I include all such modifications as within the scope otlthis patent.

When the bilge water is all ejected from the well, the ejector will act as a ventilator, as the vacuum formed will exhaust the foul air from the vessel in the same manner as the bilgewater is ejected.

Having described my invention, what I claim, andwish to secure by United States Letters Patent, is

1. In a bilge-water ejector, the combination of the bilge-well a, the ejector B, the pipe or neck f, connecting the two, and the checkvalve g, located in the neck or recess f that connects the ejector with the bilge-well, arranged to be automatically closed by the pressure of the water from the outside, whereby when the vessel is not under way the water is prevented from passing into the same through the neckf, as herein specified.

2. In a bilge-water ejector, the combination of the ejector B, the neck f, communicating with the bilge-well and connected to the ejector, the check-valve g,'arranged to be closed by the inward pressure of the Water, and the cut-off valve 12, arranged to be operated from above deck by turning the stem in case the check-valveg should become inoperative, as set forth.

3. The combination of the ejector B and the check-valve 9, located in the neck f, and provided with the float Z in the neck f at the bottom of the vessel, whereby the valve is closed and held shut by the inward pressure of the water.

In testimony whereof I aftlx my signature in presence of two witnesses.

GEORGE HAYDN.
